Smileie gives you an affordable way to straighten your teeth at home, with daytime and nighttime aligners made in the USA. If you're near their Flagstaff, Arizona scan center, you can even skip the impression kit and get a digital scan instead. Their prices start at $599 for a single arch and go up to $1,499 for the Smileie PRO package, which includes in-person scans and unlimited refinements. You'll get a whitening kit, at least one set of retainers, and a results guarantee - if you follow all the requirements, including uploading photos every two weeks. While Smileie doesn't have an "A+” rating with the BBB yet, it's mainly due to how new they are, and their customer reviews on Trustpilot are overwhelmingly positive. Some minor website typos might give you pause, but overall, Smileie gets our recommendation as the most well-priced, reliable option if you're considering at-home teeth straightening.

This UK-based provider offers plans to US customers, with pricing starting at $825 for a single arch or $945 for a dual arch in the All-Day plan (22 hours per day for 3-5 months) and $875/$1,095 for the Nightlong plan (10 hours per day for 5-7 months). Your application includes unlimited teeth aligners, a set of retainers, free shipping, unlimited remote consultations, and the ability to pay with HSA/FSA funds. While Caspersmile has a solid 4.8-star rating on Trustpilot, most reviews come from UK customers, and not many of them reference the experience. However, their satisfaction guarantee - promising to fix your smile at no extra cost if you're unhappy - sets them apart from many competitors. If you're open to trying a newer name in the US market, Caspersmile could be worth a closer look.

Where Can You Buy the Best Teeth Aligners?

Teeth aligners have revolutionized the way people straighten their smiles. Unlike traditional braces, which use metal brackets and wires, aligners are clear, plastic trays custom-made to fit snugly over your teeth. They're virtually invisible, removable, and generally more comfortable than braces, making them a popular choice for anyone looking to correct their smile discreetly.

But how do aligners differ from braces, and what's the deal with at-home aligner companies compared to in-office options like Invisalign? Let's break it down. Braces are typically recommended for more complex orthodontic issues, as they provide precise control over tooth movement. Aligners, on the other hand, can be done at-home or in a dentists office.

Teeth Aligner FAQ

Teeth aligners are clear plastic trays designed to straighten the teeth. Customers use these instead of traditional metal braces. They can be easily removed for eating and drinking.
Teeth aligners work by using a series of custom-made clear plastic trays that gradually shift and straighten teeth over time. The trays are designed to fit snugly over the teeth and each one is slightly different from the last, with subtle adjustments to gradually move the teeth into the desired position.
Teeth aligners are generally considered safe when used under the guidance of a licensed dental professional. They are made from medical-grade materials and have been approved by regulatory agencies such as the FDA. Some people may experience mild discomfort or irritation during the initial adjustment period, but these issues usually resolve quickly. It is important to follow the instructions given by your dentist or orthodontist to ensure the safe and effective use of teeth aligners.
The time it takes for a teeth alignment process varies based on type of aligner and each individual person. Regular clear aligners take approximately 4-6 months to reach desired results. Nighttime aligners take longer to achieve results. You can expect these to take approximately 10 months.
Patients typically wear each tray for two weeks before switching to the next one in the series until the treatment is complete. The aligners should be worn for at least 22 hours a day to ensure optimal results. There are also nighttime aligners which can be worn for 10 hours a night.
Teeth aligners are generally less noticeable than traditional braces and can be removed for eating and cleaning. They may be more comfortable to wear, with less irritation to the mouth and treatment time may be shorter for minor tooth movements. On the other hand, traditional braces are typically more effective for complex tooth movements and severe misalignments, require fewer adjustments and may require less discipline to wear consistently, may be covered by insurance more frequently than teeth aligners, and can serve as a visible reminder to keep up with good oral hygiene habits.
Numerous companies offer sale prices on their teeth aligners. Some also offer free shipping or extra products for free such as teeth whitening.
When using at-home teeth aligner kits, you will be assigned a medically trained doctor to oversee your case. Most companies have you send pictures of your dental progress. They monitor and make changes to your treatment plan as needed.

Braces are fixed in place, meaning you won't need to worry about wearing them as instructed - but they're also more noticeable, and they're not the easiest to keep clean (which can lead to more cavities down the road). Aligners, on the other hand, work best for mild to moderate corrections. Their removability makes it easy for you to maintain good oral hygiene, but they require commitment: you'll need to wear the daytime kind for 20-22 hours a day for the best results (or 8-10 hours for the nighttime option, with a longer total application time). Fortunately, if you're disciplined, aligners can be just as effective as braces for many cases.

When it comes to aligners, you have two main options: traditional in-office procedures like Invisalign, and direct-to-consumer (DTC) options that let you manage the process from home. Invisalign is often administered by orthodontists, who monitor your progress closely with regular check-ins. This professional oversight can be a comfort, especially for more complex cases or if you're concerned about your results. However, it also comes at a much higher price point: expect to pay at least $5,000.

In contrast, at-home aligner providers cut out the office visits. You start by completing a mail-in impression kit or visiting a scan location, and everything else - your plan, progress checks, and customer support - happens remotely. This DIY approach is usually more affordable and convenient, making it a great option for busy people who want to save money. While you won't have the same in-person care as with Invisalign, all reputable at-home aligner companies have licensed dental professionals reviewing your case and providing support.

If you're considering teeth aligners, here are five criteria to help you choose the right provider:

  • Cost. Compare the price of aligners, including additional costs like retainers, whitening kits, and impression kits.
  • Timeline. Check how long the typical process takes and whether it fits your schedule and goals. Choose a company that doesn't overpromise how quickly they can line up your smile.
  • Flexibility and support. Does the provider offer financing options, refunds if you're not a candidate, and easy ways to get help during your process?
  • Guarantees. Some teeth aligner providers promote their "guarantee”, but the only thing they're promising is to refund your money if your impression kit doesn't make you look like a suitable candidate. Some of the best companies, on the other hand, promise to stick with you until your smile is exactly how you've pictured it - including any needed refinements as part of your cost.
  • Reputation. Look for reviews and ratings, particularly about customer service, results, and support during your process. This is probably the most important factor, besides price, when choosing which teeth aligners to go with. Make sure that the company has lots of (verified and legitimate) positive feedback from happy clients.
